Failed to build for release on Windows latest runner: `defines.h:43:11: fatal error: 'strings.h' file not found\n")`

[setoelkahfi]

I have a Tauri project and got a compilation error on Windows's latest runner:

error: failed to run custom build command for `rb-sys v0.9.100`
Caused by:
  process didn't exit successfully: `D:\adesktop\src-tauri\target\release\build\rb-sys-ef992799c55b6db2\build-script-main` (exit code: 101)

Initially, I thought it was because of a mismatch in the Ruby version, which used version 3.0.0 by setup-ruby action. Now it's the correct ruby, but it still has the same errors. Any clue?

[ianks]

So you have a link to the build? It looks like it's having issues finding the correct header files for some reason, which should be configured

[setoelkahfi]

@ianks, it's a private repo. But I can share the workflow file sometime today. I posted the question on SO as well with a more detailed description.

[setoelkahfi]

@ianks updated to include my workflow file. Now I remember, I haven't tried adding some dependency like for the Ubuntu one.

[setoelkahfi]

I didn't solve this; instead, I removed magnus from my crate dependency since I don't use it. I used it on a Ruby gem with a Rust extension.
